Image display method and associated apparatus

Abstract

An image display method includes: receiving an original frame having an original image data part; adjusting the original frame to generate an adjusted frame having an adjusted image data part and a non-image data part, wherein, the adjusted image data part comprises a plurality of pixel lines; and scanning image data of N number of the pixel lines of the adjusted image data part to generate data of N+K number of pixel lines of a scanned frame. N and K are positive integers. The original frame has a same size as that of the adjusted frame; and the adjusted image data part has a size smaller than that of the original image data part.

What is claimed is: 
     
         1 . An image display method, comprising:
 receiving an original frame having an original image data part;   adjusting the original frame to generate an adjusted frame having an adjusted image data part and a non-image data part, wherein, the adjusted image data part comprises a plurality of pixel lines; and   scanning image data of N number of the pixel lines of the adjusted image data part to generate data of N+K number of pixel lines of a scanned frame, wherein N and K are positive integers;   wherein, the original frame has a same size as that of the adjusted frame; and the adjusted image data part has a size smaller than that of the original image data part.   
     
     
         2 . The image display method according to  claim 1 , wherein the adjusted image data part and the adjusted non-image data part occupy one-half of the adjusted frame, respectively. 
     
     
         3 . The image display method according to  claim 2 , wherein the adjusted image data part is a front half of the adjusted. 
     
     
         4 . The image display method according to  claim 1 , wherein the non-image data part comprises at least one of information types of a black image, a grayscale image and no data. 
     
     
         5 . The image display method according to  claim 1 , wherein the step of adjusting the original frame to generate the adjusted frame comprises:
 down-scaling the original image data part as the adjusted image data part.   
     
     
         6 . The image display method according to  claim 1 , wherein the original frame has a same size as that of the scanned frame. 
     
     
         7 . An image display apparatus, comprising:
 an adjustment device, configured to receive an original frame having an original image data part, and to adjust the original frame to generate an adjusted frame having an adjusted image data part and a non-image data part, wherein, the adjusted image data part comprises a plurality of pixel lines; and   an image scanning device, configured to scan image data of N number of the pixel lines of the adjusted image data part to generate data of N+K number of pixel lines of a scanned frame, wherein N and K are positive integers;   wherein, the original frame has a same size as that of the adjusted frame, and the adjusted image data part has a size smaller than that of the original image data part.   
     
     
         8 . The image display apparatus according to  claim 7 , wherein the adjusted image data part and the non-image data part occupy one-half of the adjusted frame, respectively. 
     
     
         9 . The image display apparatus according to  claim 8 , wherein the adjusted image data part is a front half of the adjusted frame. 
     
     
         10 . The image display apparatus according to  claim 8 , wherein the non-image data part comprises at least one of information types of a black image, a grayscale image and no data. 
     
     
         11 . The image display apparatus according to  claim 7 , wherein the adjustment device is a scaler, and the scaler down-scales the original image data part as the adjusted image data part. 
     
     
         12 . The image display apparatus according to  claim 7 , wherein the original frame has a same size as that of the scanned frame. 
     
     
         13 . The image display apparatus according to  claim 7 , wherein the adjustment device is integrated in a motion estimation and compensation device. 
     
     
         14 . The image display apparatus according to  claim 7 , wherein image scanning device is integrated in a display driving unit of a display.
